Ok well what I was wondering was... It's hard to go by the charger lite when it flashes green and red, like I said, my wall charger shows solid red when charging, and solid green when my regular 650mah bats are fully charged. When I went to charge the new spinner, the LED button remained on (which you said was normal) but then it went off a few minutes later. Then my wall charger light flashed green and red, which I've never seen before.
Anyways, I took it off the charger (I'm assuming it's fully charged) and am using it now. So far so good, got it set right between 3.3 and 3.8 volts, with a 1.8ohm
coil head... working good!
